Patent GB-902112-A (GB)
Abstract: 902,112. Gas igniters. HORSTMANN GEAR CO. Ltd. April 13, 1961 [March 28, 1960], No. 10851/60. Classes 75 (1) and 75 (3). [Also in Group XXIX] In a gas-lighting appliance wherein a taper 11 attached to a flexible supply tube 15 is carried in a holster 10 connected to a conical plug valve 8 controlling the gas supply to the taper, a sheet metal shield 29 mounted on the valve body 1 surrounds a pilot burner 7 on the valve body and provides a flash chamber 30 for igniting the taper from the pilot burner. The valve body 1 is attached to the gas pipe 5 of a gas stove by a threaded union 4. The valve 8 is urged by a spring 22 against a conical seating 19 formed in a passage 18 within the valve body 1. Gas from the passage 18 passes into a bore 25 within the valve and then through ports 27 to an arcuate slot 26 in the conical surface of the valve to the pilot burner 7. When the taper 11 is rotated from its vertical rest position to a horizontal position, thereby rotating the valve 8, a further port 24 in the valve registers with a port 17 in the valve body to supply gas to the taper 11. The shield 29 comprises a pair of parallel wings secured to flat faces on the valve body and side pieces 38 forming a shroud enclosing the pilot burner 7. The wings extend into a scoop-like part forming the flash chamber 30. When the taper 11 is in the vertical position it is retained in the holster 10 by a projecting finger 31 on the valve body which engages a conical head 12 on the taper. The Provisional Specification describes a lighting appliance wherein the gas supply to the taper is controlled by a spring-loaded piston valve slidable within a valve body and operated by a cam on a spigot on the holster. A spring-pressed ball in the holster engages an annular groove around the taper to retain the latter.

Title: A semiconductor device
Inventor: KOMARU MAKIO
IPC: H01L23/66
Filed: 1991-05-15
Abstract: A semiconductor device for a high-power output amplifier and having a substrate (4) with a reduced thickness, an electrode for heat radiation being provided on the rear surface of the substrate, includes a metallized pattern (13) produced by a metal plating layer surrounding the periphery of the element, the side surface of the element, and the electrode for heat radiation except for the neighborhood of high-frequency input/output portions (8,9). Therefore, it is possible to prevent the element from becoming fatally defective because of small cracks and chipping due to die-bonding operation. Also the soft soldering material climbing onto the surface of the element can be prevented from contacting the metal film at the input/ output portions. Furthermore, short-circuiting does not arise during wire-bonding, thereby enabling to enhance the yield at assembly and the reliability of the element, and to reduce the production cost. <IMAGE>

Title: Extinguishing and controlling fires
Inventor: POWELL BRIAN DAVID
IPC: A62C3/08
Filed: 1991-12-20
Abstract: Apparatus for extinguishing or controlling fires in the cargo bay (6) of aircraft is disclosed. Water from a tank (8) is used as the extinguishing agent. An initial fire hazard may be detected by means of a smoke detector which activates a control unit (14) to cause an initial relatively short-duration water spray discharge into the cargo bay (6) through one or more spray lines (12). One or more parameters within the cargo bay (6) are then thereafter monitored (for example, temperature, infrared radiation, concentration of one or more particular gases) so as to detect if and when a fire hazard re-arises. When this is detected, a further relatively short-duration water spray discharge takes place. In this way, smouldering fires, which are the most common types of fire in an aircraft's cargo bay and which are difficult to extinguish completely while the aircraft is in flight (because of the limited quantity of extinguishant which can be carried), can at least be controlled until the aircraft lands.   <IMAGE>

Title: Liquid dispensing : metering accuracy
Inventor: KNUBLEY JOHN SANSBURY
IPC: F16N37/00
Filed: 1992-06-06
Abstract: In a dispenser for liquid lubricant, air-actuated pump 13 pumps lubricant 10 from reservoir 11 to one or more dispensing stations 17. Lubricant flow meter 18 provides an outlet indicative of the volume of lubricant 11 and includes a flow direction detector for providing an output indicative of said flow direction. An indicator for indicating the volume of lubricant 11 dispensed by any one of the dispensing stations 17 gives positive flow values when the flow direction detector indicates that lubricant flow is in the desired direction and negative flow values when the detector indicates that lubricant flow is in the reverse direction to the said desired direction. This combats the problem of fluctuation in the pressure of air driving the pump causing reverse lubricant flow. <IMAGE>

Title: Method and apparatus for smoothing mud return fluctuations caused by platform heave
Inventor: BAILEY MARSHALL GRAHAM
IPC: E21B21/00
Filed: 1992-09-11
Abstract: A drilling platform having a marine riser (12) extending down to the sea bed comprises a fluid outlet in the form of a feedpipe (38) connected to a manifold (49). The manifold is held fixed to the sea bed by a tensioned wire (42) and delivers the returning fluid mud via a flexible hose (46) to a shale shaker or other mud treatment facility. The mud may 28 alternatively be indirectly discharged from the manifold via a collection tank (80) and pump (82). One of the parameters under constant surveillance is the flow rate of the returning drilling mud, since any sudden change in the return flow rate may indicate for example an influx of gas or fluid into the borehole. Unfortunately the variation in flow brought about by the rise and fall of the telescopic upper section of the marine riser can be such as to mask any variations in flow rate and thereby render instantaneous flow rate monitoring almost useless. The effect is a function of heave amplitude and rate, and becomes dominant for low pump rates. <IMAGE>
